This week’s infographic comes via OnlineColleges.net and takes a look at the rising cost of textbooks.

I simply don’t believe that college textbooks increased by 186% in 2004 alone!
The graph surely represents cumulative increase since 1986, but it does so in a rather sloppy way.

I thought the graph showed the cumulative increase over time, not proportional.

Yes, that’s what it looks like, but the graph is labelled ‘annual percentage increased’.
The data might well be correct, but when it’s presented in such a sloppy fashion it’s hard to take it seriously.

What a great, unintentional example of the kinds if poor presentation you are likely to get without a professional author and editorial team. You don’t see this in professional textbooks. Perhaps you do get what you pay for.

You must not follow the same textbook publishing circles I do. This kind of mistake is less uncommon in paid textbooks than you might think.
And what makes you say that the folks who release an OEM textbook aren’t pros?
